Every carrier on SJC to HNL, 807 flights
These figures cover 242 flights between September 2025 and August 2026. The median arrival is 8 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Carrier by carrier
Alaska against every carrier on SJC to HNL
Alaska flew 242 of the 807 flights on SJC to HNL, about 30% of it. Its 84.3% on time is 4 points better than the route as a whole, which runs 80.4%. Ranked by on-time rate it is number two of three carriers on the route, where the range runs from Hawaiian at 90.0% to Southwest at 75.6%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.
Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

Departure window
When Alaska runs best on this route
Departure time is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 242 flights.
- 5am–8am89 flights88.8%
- 8am–11am153 flights81.7%
- 11am–2pm—
- 2pm–5pm—
- 5pm–8pm—
- 8pm–5am—
Scale runs 75% to 95%. Rows with fewer than 30 flights show a dash.
The early departures do better, though not dramatically: 88.8% on time for the 5am–8am window against 81.7% for 8am–11am. Worth taking if the schedule allows, not worth an extra connection. The 8am–11am window is the busiest, with 153 flights scheduled in it.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 84.3% on time across 242 flights.
Alaska on SJC to HNL did not run the same all year. Its best quarter was Jan–Mar 2026 at 93.3% on time and its weakest Jul–Sep 2026 at 64.5%, a swing of 29 points on roughly 81 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.
Across the week, Friday is the strongest day at 91.4% on time and Tuesday the weakest at 76.5%, a spread of 15 points.
Arrival by arrival
How late Alaska on SJC to HNL runs when it is late

Share of 242 completed flights by arrival against schedule.
A late pushback is often recovered here: of 20 departures that left 15 minutes late or more, 6 still arrived on time. In the other direction, 24 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at HNL.
The worst days
Worst days for Alaska on SJC to HNL
The latest arrival of the period was on 29 March 2026, 3 hours 35 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. On four of the five worst days the largest share was filed as carrier-caused (crew, maintenance, fuelling, baggage).
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 29 March 2026 | 3 hours 35 minutes | Late-arriving aircraft |
| 25 August 2026 | 3 hours 18 minutes | Carrier |
| 8 July 2026 | 2 hours 32 minutes | Carrier |
| 21 April 2026 | 2 hours 7 minutes | Carrier |

Delay causes
Why Alaska runs late on this route
Carrier accounts for 52% of the 1,896 delay minutes carriers reported here, and the remaining four split what is left.
- 52%Carrier
- 36%National Airspace System
- 11%Late-arriving aircraft
- 0%Extreme weather
36% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 687 minutes out of 1,896, against a national NAS share of 21%. The split is drawn from 1,896 reported delay minutes.
The largest share of delay minutes, 52%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 988 of the 1,896 delay minutes reported here.
Cancellations are rare at 0.00%, below the national 1.89% and low enough to earn the plus on the grade. Almost no flights are called off; the risk here is arriving late, not not arriving.
Connections and stage length
What a delay here costs
Badly late arrivals are rare here: only 3.7% land an hour or more behind schedule, against 8.3% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
At 2,417 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.
The return leg is a different operation and performs like one: it runs 72.4% on time across 243 flights, 12 points below this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 12 points of difference.
One caution: this is a thin sample. 242 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.
What to do with this
Booking Alaska on SJC to HNL
Put together: treat all of this as provisional. 242 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 84.3% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 242 completed flights over 12 months sit behind that.
